Subj:   Will the 2 SQLs return the same values....

Is there any difference in the 2 SQLs.

The problem is that in the 1st SQL, I got only 2 Values for Service and the whole action happens on just 2 AMPS and it becomes skewed.

I then changed it to be a SubQuery. Are they both the same.

SELECT ast.id, max(wm.stat) AS codes
   FROM  ast  LEFT OUTER JOIN  wm
     ON
 ast.id = '0000'
 AND  ast.service = wm.service ;


SELECT ast.id, max(wm.stat) AS codes
  FROM ast LEFT OUTER JOIN  wm
    ON
ast.id = '0000'
AND ast.service_group in (sel service from wm) ;

Thanks a Million.
